When consent to cull and/or survey was not obtained (Table 2), trapping along the boundaries of the parcels for which consent was refused allowed staff to catch a proportion of the badgers residing in the no-access farm.
When there is a probability of getting caught, the proportion that does not offer a bribe increases to 50%%.
Governments then awarded licences to catch a fixed proportion of the quotas.
Of the legal eel catch, a certain proportion of live glass eels is supposed to be set aside each year for purchase by European countries who, instead of consuming them, put the fish towards the restocking of their eel-depleted rivers.
Because Irish trawler crew have traditionally worked as share fishermen – a system whereby workers are paid a share of the money made from the catch, divided in proportions agreed by the owner – they have generally been considered self-employed and responsible for their own tax and insurance.
The proportion caught was calculated only for length bins for which more than 3000 fish of all ages or 2000 fish of ocean ages 2 or 3 were caught on a given day to prevent inaccurate results due to small sample sizes.
For each year that data were available, we calculated exploitation ratio (total proportion caught) for fish of each age group (all ages, ocean age 2, and ocean age 3) and sex on a yearly basis (P y, a, s ) (equation 1).
However, the proportion of catch in this category has declined from around 50% of global catch to around 35%, presumably due to better reporting of ray catch and as sharks have declined or come under stronger protection.
But there's a catch: The apparent low proportion of deaths probably depends more on the way health officials are calculating the number than on the deadliness of the virus or the quality of care patients are receiving.
The proportion of catch from Islas Robinson Crusoe and Santa Clara was estimated to be 65% (±5% standard deviation) from 1972 1983 [50] and 49% for the 1996 1997 season [49].
For the "fishing" period, we assumed that catch represented a smaller proportion of total stock biomass because CPUE was higher during this period [50].
